/**
* The HACK computer, including CPU, ROM and RAM.
* When reset is 0, the program stored in the computer's ROM executes.
* When reset is 1, the execution of the program restarts.
* Thus, to start a program's execution, reset must be pushed "up" (1)
* and "down" (0). From this point onward the user is at the mercy of
* the software. In particular, depending on the program's code, the
* screen may show some output and the user may be able to interact
* with the computer via the keyboard.
